WRAPPING- MACHINE.

srEcIFrcAzrroNforming para of Letters `Patent No. 697,617, dated April 15, 1902.

Application nea A'p'rii 24, 1901'.-

To @ZZ whom it ntcty'conoern:

Be it known that I, GEORGE LEwIs GAY, a citizen of the United States, residing 'at Spo# kane, in the county of Spokane, in the State of Washington, have invented certain new and useful Improvements in Wrapping-Machines, of' which the following is a specification.

My invention relates to a machine for folding and wrapping newspapers and analogous packages-such as pamphlets, periodicals, and other printed matter requiring the application of a Wrapper or band for transmission through the mails.

It has for its object to provide mechanism for neatly and snugly folding the paper or pamphlet with the wrapper properly wound in and around it andits outer end'sec'ured by adhesive paste. In the present invention certain improvements overa former patent granted -to me October 3, 1899, and numbered 634,333, are contemplated, particularly in the intermittent motive mechanism for operating the folders and in the clamping-formels between which the paper is folded and wrapped. Further improvements are comprised in `the pasting and sealing mechanism and in the novel construction, arrangement, and combination of the parts of the machine, as hereinafter more fully described and claimed.

In theaccompanying drawings, forming a part of this application, Figure `l is kan end elevationof myimproved wrapping-machine. Fig. 2 is a vertical lengthwise section on the line X X of Fig. 1, showing the mechanism partly in front elevation, but with one end only represented, the other'being a reversed duplicate thereof. Fig. 3 is a vertical crosssection on the line y y of Fig. 2, but showing the shafting of the lower part of themachine in section on the line Z Z of said figure. Fig. 4 is a central vertical cross-section of the upper part of the machine through the wrapping and astinU mechanism. Fig. 5 is a' length` wise section through Fig. 4 on the line X Y. Fig. 6 is a plan of the pasting-cylinder viewed in the direction from X to Yin Fig. 4L Fig.` 7 is a plan View of the comb or guide for coni ducting the wrapping-paper from the feedrolls to the wrapping devices. Figs. 8 and 9 are respectively upper and lower plan views' Serial No. 57,199. (No model.)

of the segmental roll. Fig. l() is a view of the paper-roll bracket and support.

Referring to the drawings,A designates the uprights comprising the frame of my improved wrapping-machine and which are secured together by the cross-bars a', bolted to their lower portions, and the tie a2, connecting the upper' parts thereof and having its ends reduced and shouldered where they pass through the uprights and fitted with nuts a3, received in countersunk pockets a4 on the outside of the frames. The lower transverse girder portions B of the uprights are provided end 'pivotally connected by a wrist-pin d to a segmentalv rack d2, fixed upon a shaft d3,

-which is supportedin the bearings d4 and caps d5 on the rear edges of the frames. By means of the said connecting-rod'therotary motion of the drivingshaft and crank is adapted to impart a vertical reciprooation or oscillating movement to the segmental rack d2.

Onthe side of the machine opposite the shaft cl3 is journaled a shaft E in the bearings e and caps e2. Loosely mounted on said shaft E is a sleeve e3, provided with a ratchet-disk e4 and a'pinion e5, intermeshing with the seg- `mental rackdz. An arm F is rigidly fastened ou the shaft E, carrying a pawl f', actuated by a spring f2 and adapted to engage a single ratchet-tooth or driving-shoulder f3, forming one. side of a notch f4, cut in the periphery of the said ratchet-disk. By means of this construction the pinion e5 is caused to rotate idly and independently of the shaft E during the upward throw of the crank b4 and segmental rack; but with the downward stroke of the said parts and consequent reversed motion of Ithe pinion in the directionof the arrow marked thereon in Fig. .3 the pawl f will be engaged by the drivin g-shoulder f3 of the ratchet-disk y'and revolved in the direction indicated by saidfarrow. A single` ratchet-tooth on the fdisk is vsufficient when, as shown in the drawings, the pinion is proportioned to make exactly one revolution with one stroke of the segmental rack.

On each end of the shaft E, adjacent the outside of the uprights A, a gear-wheel G is secured, which gears are adapted, by means of the crank motion and pawl-and-ratchet mechanism aforesaid, to rotate in the direction of the arrow thereon one half of the time and to remain motionless and idle the other half of the time, starting and stopping, respectively, with the gradual acceleration and retardation peculiar to pitman movements. Intermeshing with the gears G are the pinions g', having the journals g2 loosely fitting in the circular bearings g3 in the frame and adapted to turn upon antifriction balls g, placed around said journals in circular grooves g5 in the uprights and bearing also against the back or inner surface g6 of the pinions. The pinions are held from the opposite direction by caps gT g8, set over their upper and lower edges and bolted to the uprights. The proportions of these gears are such that the single revolution of the gear-wheel G produces several revolutions of the pinion g', being in the construction shown exactly two and a half in number.

At each end of the machine, secu red in each cap gs, are two horizontal rods H, connected at their outer ends by a yoke 7L', which also extends downward to form a brace h2, having its lower ends bolted to the frame. Said rods form guides on which heads h3 are adapted to slide, operated by the vertical levers 7L, pivoted to the brackets 715, extending from the uprights. The levers are connected by a spring 7LG above the brackets, the tension of which normally acts to draw the upper ends of the lever and the heads 71.3 toward the frame. Said heads are operated in the reverse direction by disk-cams 7L7 on the outer ends of the driving-shaft b3, outside of the lever and adapted to bear upon a friction-roller h5 at the lower c nd 7i9 of the lever.

Journaled in each head 7b3 in the axial line of the pinions g is a short shaft t', having shoulders t" on each side of its bearing in the head and provided with a lug i2 on its inner end, to which the folders or plates s are riveted. Said folders are of about the width co1'- responding to the desired width of the fold of the newspaper when wrapped, and they are passed through a rectangular aperture 4 in the pinion g', by means of which they are revolved with the shaft t' by the rotation of the said pinions. The folders are of spring-steel and are set with such an amount of are that they are under considerable tension when inserted through the rectangular aperture of the pinion. They are of such length that when carried inwardly to the extent of their throw their ends reach nearly to the central plane of the machine. Hence they almost meet at that point.' At the outer limit of their throw the saidinner ends project slightly interiorly to the inner faces of the uprights, as shown in Fig. 2. Vedge-shaped cams t5 are riveted to the outer sides of the folders and adapted by engaging corresponding inclined abutments G on the pinions g to cam the folders together at the inner limit of their throw.

ln the upper part of the frame is journaled a hollow cylindrical roll K, having an opening 7c in its periphery, as shown in Fig. 4. In one end of the said roll is rigidly secured a short shaft 7a2, which is journaled in the box 7c3 in the frame, and at the opposite end a similarly-proportioned shaft 7a4 is loosely iitted in the hub 765 and firmly secured in the box 7i:G of the upright. The'roll therefore is adapted to rotate upon the shaft 7.:4 as a center, while the shaft 7a2 rotates with the roll in its bearing 7c3 in unison with and driven from the driving-shaft b3 by means of a sprocketgear k7 thereon and chain 708, connecting the same with a similar gear on the shaft 7a2.

The ends of both the fixed and movable rollshafts project within the cylinder, as shown in Fig. 5, and support a tank L, which is held in a stationary position bya pin 7 in the immovable shaft 7t4 engaging a corresponding recess 72 in the bearing 3 of the tank upon said shaft. The opposite or movable shaft 7c2 turns in its bearing Z4 on the tank, and a gear 75 is fixed upon it and intermeshed with a pinion Z on a shaft Z7, jonrnaled in the upper edge of the tank L. Said shaft is rotated by the movement of the gear 75 as the cylinder turns, and a belt 78 is carried by an elliptical drum Non said shaft, which belt tracks upon a weighted pulley M, rotating at the bottom of the tank. The pulley is of the length of the interior of the tank and is provided with anges m at its ends, which serve to hold the belt in place thereon and on the drum above. The tank is inserted into the roll K through the opening 7c in its periphery, and its function is to hold the paste for sealing the wrappers, to which the paste is conveyed by the belt Z8, as hereinafter described. The tank may extend quite across to the opposite side of the cylinder and may hang to one side of the center thereof, if desired.

A segmental roll or semicylinder M2 of the same diameter of the roll K is fixed upon a shaft m3, journaled in the boxes m4 in the extreme upper part of the machine, and the two rolls are geared together and driven in unison by the gears m5 and-m, of equal diameter, respectively keyed upon the shafts 702 and ms, which are set equidistant from the axis ofthe folders. These rolls are thus adapted to feed the newspapers to be folded and also the wrapping material 768 between the folders, along the plane passing through the axis thereof and the points of contact of the feed-rolls. An incline m13, set on this plane above the rolls, acts as a guide to direct the papers between the rolls, and a table mi, supported on arms m15, hinged to the frame, is provided, iu connection with the incline, as a repository for the papers previous to being fed into the machine. The table and incline are held in their working position by the lugs m1 setting upon the upper surface of the uprights and IOO IIO

engaging the studs m7, inserted in said snrface, but from which the lugs may be readily lifted and disengaged to swin g the tableframe down from over the rolls for access thereto. The roll of wrapping material m8 is mounted on centers m9, projecting inwardly from said brackets, and one of which is movable lengthwise in its socket for the purpose of inserting and removing the roll therefrom. Said movable center N is held to the roll by a spring n', and the centers are fitted with disks n2, which by their pressure against the en'ds of the roll due to the pressure of the spring n retard the roll and insure the proper tension of the wrapping material. To the lugs m19 is preferably secured a guard m91, partly overhanging and shielding the feedroll M2.

The wrapping material ks passes to the feedthe incline, is hung against said edge n4, heldV by the counterweight n? on the upper end thereof. Said gate retains the newspaper on the incline until the feed-rolls reach the position when the paper should be entered between them, at which time the gate is tripped by a projecting segmental rim w19 on the end of roll K engaging an arm ns, depending from the gate in the path of the arm. The arc through which the rim extends determines the length of the interval'through which the gate remains open. The gateprojects downward below the edge of the incline and is armed at its lower edge with a rubber orelastic lip 719,'which impinges upon the roll and serves as a check against backward slipV of the wrapping material. A similar cheeky'l is hung on a bracketj2 below the incline, bearing upon the Wrapping materialen the roll at a distance from the lip a9 somewhat greater than the width of the opening k in the periphery of the roll, the purpose of said check being to retain a hold upon the wrapping'material during the time when the lip 77,9 is renderedv idle and non-resisting by the passing beneath it of the opening 7c in the periphery of the roll, thus releasable by the movement of the wrapping material in the direction of the feed, but clamping by the backward pull thereof, .whereby the two checks combined insure uninterrupted hold upon thewrapping material. l

Upon the leading edge of the segmental roll M2 is secured a paper-cuttin g knife 3'3, adapted through its serrated edge j4 to perforate and sever the wrapping material at each revolution of the roll by impingement upon an elastic bed ji", of rubber or other suitable material, set in a barj9 on the roll K at the followingedge of the opening c, whereby the wrapper is cut off just back of the point where the paste is'applied by the belt Z9 as the hi ghpart j of the drum Z9 sweeps under the wrapper. To bring the drum` to this position coincidently with thel arrival of the opening itV at that point, the gears Fl require to be of equal the serrated edge of the knife.

continued rotation ofthe folder.

Just back of the bar jand practically forming part of the periphery of the roll K is a segmental rocker r of somewhat greater curvature than the roll and hinged thereto at the ends to rock slightly from a point near its central longitudinal plane as an axis. Its leadin g and following edges, which project slightly above the periphery, respectively comprise a series of tongues r2 r3, and in the rotation of the feed-rolls, when the leading edge r9 passes under the roll M2, the following edge 'r3 will be correspondingly lifted, as shown in Fig. 4. Later, when the axial plane of the rocker reaches the plane of contact of the rolls, the strain of the wrapping material thereon will depress the rear edge of the rocker and lift the leading edge, thus relieving the forward edge lof the wrapper from the roll and detlecting it toward the folders. A similar rocker T5 is carried at the leading edge of the roll M2 back of the knife j, which, as its following edge r9 bears upon the roll K, is lifted at the front edge W and insures clearing the paper from The tongues of the rocker r9 are preferably fewin number to reduce the number of. the elastic strips r necessarily placed betweenA themv to provide an elastic frictional surface for bearing upon the roll K. The said strip occupies. only a small arc of the periphery of the roll, .just sucient to feed .the free end ofthe wrapping material so far between the rolls thatit will not become displaced during the following non-feeding interval while the wrapping of the preceding paper is being completed, an interval corresponding to the clearance-space r9 following the strip. On the opposite side IOO IIO

of said clearance and extending tothe following edge of the roll M2 is a seriesof elastic strips r9,'which are adapted to complete the feeding in of the wrapper to where itis grasped -by the folders, and outside ofsaid strips and the path of the wrapper are the similarly elastic strips T, extending through a longerarc, for feeding the newspapers between the rolls.

Between the axis ofthe folders and the point of contact of the feed-rolls secured to and extending across betweenthe-uprights is a comb t', set with its upper edge in juxtaposition tothe periphery ofthe roll K. The teethof the said combare proportioned to permit the passage between them of the tongues of the rocker r', whereby thecomb is adapted to receive the forward Yend of the wrapping-paper from off the rocker as the tongues r2 thereof pass through the comb. The comb is set at the proper angle to guide the wrapper between the folders t2.

Arranged on each side of the folders are the clamping-formers 2192, which are fiat plates fastened upon arms t t5, which are hung on studs t6 t7, just inside the frames on each side of the machine and adapted to close together on the folders at substantially right angles to the plane through the axis of the folders and the contact-line of the feed-rolls. Said arms are of unequal length, the shorter arms i* having spurs 258 extending on the opposite side of their fulcrums and impinging upon bearings t9 on the longer arms t5 about midway between the pivotal centers of the arms. The effect of this construction is that the pressure of a single spring U, bearing between the arm t5 and a lug U2 on the frame will clamp both formers together equally. Levers U2, extending from the arm t over the axis of the roll K, are lifted by cams U4, carried by the roll K, to open the formers to discharge the folded paper from between them and retain them apart until the next paper to be wrapped is fed into the machine, the movement of the arm t4 also correspondingly opening the arm 155 by means of the construction aforesaid.

Arranged below the formers in. the plane of the axis of theA folders and point of contact of the feed-rolls is a strip U5, (shown in crosssection in Fig. 3,) extending from one upright A to the other, bolted at the ends UG thereto. Said strip forms a stop to locate and right the newspapers when they are dropped between the folders preparatory to being folded. Beneath the stop is an apron U7, hinged to the tie-rod a2, which is alternately held up to the stop as the arm F passes under it and then dropped to the periphery of the ratchet-disk e4. Its purpose is to receive the folded and wrapped papers when discharged from the formers and retain them at rest for an interval to permit the paste of the sealed edge of the wrapper to set prior to the paper being dropped into a receiving-receptacle on the fioor.

Constructed as above described and shown, the operation of the machine is as follows: The folders being turned intermittently and the feed-rolls rotated continuously, the paper to be folded is first laid upon the incline m13, where it remainsheld by the gate a5 until the same is engaged by the cam n10, as shown in Fig. 1, after which the lifting of the gate will permit the paper to drop and be fed down between the rolls through a distance corresponding to the length of the friction-strips T on the roll M2. During this operation the wrapper ks, previously having been entered between the feed-rolls to an extent corresponding to the length of the arc comprised by the strips r, remains at rest until seized and fed in by the short strips r9, intermediate of the strips T. This movement carries the end of the Wrapper,which is of less width than the newspaper, and consequently not affected by the strips T, in between the folders, which meanwhile have been let in toward the central plane of the machine by the rotation of the high points U17 of the disk-cams k7 from under the cam-rolls h2 at the lower end 7i of the levers h4 and retraction of the levers by the spring h, the rolls hs at this time riding along the level surfaces U8 on the cams. Then when the edge of the segmental roll M2 passes out of contact with the roll K the newspaper will drop to and aline its edge against the stop U5 in position to be seized by the folders, which then by the travel of the rolls h2 down the secondary incline U9 of the cams will be thrust inward to their in nermost position and tightly clamped upon the central horizontal section of the newspaper and the end of the wrapping material bythe engagement of the wedgeshaped cam Z5 with the inclined abutments 6 on the pinions g. The end of the wrapper thus laps upon the newspaper through practically the upper half of the vertical length thereof in position to be wound into the folds of the newspaper in the subsequent folding and Wrapping process. At this stage the driving-crank b4 will have reached its uppermost position and on its downward stroke will rotate the folders, as hereinbefore set forth, and fold the paper around them, together with the wrapper, between the springactuated formers t2 t3, which will yield to conform to the successive edgewise and flatwise cross-sectional dimensions of the folders and their enveloping package relatively to the plane of oscillation of the formers, but will maintain a constant pressure thereon. During this action the Wrapper is drawn from the roll m8 by being wrapped around the folders, slipping easily over the surface of the roll K until it is caught between the knife j and the elastic bed l7'2 of the roll K and severed. Just preceding this operation the paste will have been applied to the lower surface of the wrapi per by the drum Z9 and belt Z8 and the pressure of the brush upon the wrapper when over the drum. Successive turns of the folders wind the said end of the wrapper upon the paper and seal the pasted edge by the pressure of the formers, after which the folders are withdrawn by the incline U10 of the disk cam and the formers are then opened by the cam Uu1 engaging the levers U3 of the arms t4 t5, and the folded, wrapped, and sealed package is dropped and deposited upon the apron U2. At the instant of being cut the part of the wrapper back of the knife is held by the strip r, bearing on the roll K, and itisfed down by said strip r sufliciently to remain in place between the rolls,while it stands at rest with the forward end lying upon the comb t during the completion of the wrapping and sealing of the detached wrapper and until the wrapper paper or pamphlet is discharged from the machine.
